A lost suitcase is inconvenient when it contains clothing and toiletries, but it can become a medical problem when it contains the prescriptions you need every day. For travelers over 60, packing medications deserves as much attention as booking flights and arranging transportation. Blood pressure medicine, diabetes treatments, heart medications, and other prescriptions aren’t always easy to replace when you’re hundreds or thousands of miles from home. International travel adds another complication: A medication that’s perfectly legal in the United States may be restricted in another country. That’s why traveling with prescription medications requires more planning than simply filling a weekly pill organizer.
